Machine wash the blanket without the inner filling with similar colours on a gentle or delicate cycle with mild liquid detergent. Air dry in the shade for best results. Avoid fabric softeners as it may add toxins to a natural product. The inner quilt can be exposed to sunlight for natural cleansing. Washing is not recommended. The natural indigo colour might bleed for the first couple of washes. Please note that Indigo colour is sensitive to citric content. Natural dyed colours evolve over time, and with long exposures to the sun. Store rolled or hung to avoid foldlines.
